SEQUIM — Firefighters were investigating Saturday the cause of a fire that broke out in a vacant house Friday night.

The house in the 200 block of South Fifth Avenue sustained smoke and water damage, and the attic was destroyed, but the structure remained intact, said Patrick Young, spokesman for Clallam County Fire District No. 3, adding that firefighters extinguished the blaze in 35 minutes.

There were no injuries, he said.

The house, which had a rental sign in the window, was undergoing renovations, Young said.

As of midafternoon Saturday, no cause of the blaze had been determined, Young said.

Sequim firefighters were dispatched to the area of South Fifth Avenue and Maple Street at 9:41 p.m. to investigate a reported odor of smoke, Young said.

While they were en route, Sequim police reported a home in the 200 block of South Fifth Avenue with heavy amounts of smoke coming out of the eaves of the roof.

The first firefighters on the scene found an attic fire in the home.

Firefighters got into the attic from inside the house just as flames broke through the roof.

The fire was contained by 10:15 p.m., Young said.

The owner of the home had not been contacted, Young said early Saturday morning, and it was unclear if the house was insured, he said.

No damage estimate was available.

About 18 firefighters from the Sequim Fire Department helped put out the fire.

Personnel with the Clallam County Public Utility District and Olympic Ambulance and law enforcement officers from Sequim and the Clallam County Sheriff’s Office were all on scene to provide assistance.
